非洲种质在黄淮海的改良与利用研究

对4个非洲种质和4个常用种质组配的16个组合的玉米穗部性状、抗病性及病害与产量的相关性进行分析。结果表明，坦桑尼亚种质ZB903所配制的组合产量表现较稳定，综合抗病性强，在抗病育种中有较大的利用价值；埃塞俄比亚种质与黄改系种质选育的CM07组配的组合产量最高、百粒重大、穗行数多，对产量影响最严重的茎基腐病表现达高抗水平。直接利用非洲种质的效果并不理想，其与黄改系种质杂交选育的自交系可在黄淮海重点利用。瑞德×（塘四平头+非洲种质）是黄淮海利用该种质比较理想的杂种优势模式之一。

Africa Germplasm Improvement and Utilization and Research in the Huang Huai Hai

Compared with panicle traits, disease resistance, and correlation analysis of disease and yield among 16 groups from four African germplasm and four common. The results showed that the group of Tanzania germplasm ZB903 had stable yield, disease resistance, great use value in disease-resistant breeding; the group of CM07 from Ethiopia germplasm and improved lines of Huangzaosi performs best in yield, row number per ear, 100 grain weight and high resistance to Fusarium monjliforme. Reid ×(Tangsipingtou + African germplasm) is one of the best modes, so we can focus on the hybrid breeding between improved lines of Huangzaosi and African germplasm which dosen't grow very well alone in Huanghuaihai's region.
